I understand the value in taking time off when you have an infant; get settled in, get the routine down, get the mother healed up, etc. An infant that old doesn't understand "daddy" yet. That'll take a month or so when they become more 'aware' of dad and his voice, so there really isn't this all magical bonding time that work interferes with for the man.
Now with that said, I think people misunderstand the positions that some are arguing on here. It isn't to say that people shouldn't get the time off. It's to say that they shouldn't get PAID time off. There is a huge difference here and I can understand the rub for people that may be unable to have children, or choose not to have children.
Personally I think that only the mother should get any sort of leave, after all she's the one in the hospital undergoing the ordeal. Unpaid of course, because if you are trying to have a family then you should be responsible enough to have banked enough money to save for the mother's leave. Having a child shouldn't be on the backs of someone else, it is your decision (a big one) and your life, take responsibility.
